XAPPR Gun

Can’t say we ever thought we’d be playing simulated first person shooters on our iPhones, though we have to admit that it does make sense what with the built-in gyroscope and all. Strap your iPhone to a XAPPR gun and start shooting down aliens or bugs in a [slightly more] realistic way. Trigger presses are registered and sent to the iPhone via an auxiliary cable into the headphone port, though you’ll need a XAPPR-enabled game to really use it.
